Wierd Glitchy Render
It looks like you textured your model using the Textured Mode. The problem is that those settings don't transfer back to your material settings. For example if you have the face and the clothes on different textures Textured mode will allow you to unwrap some faces on one texture and others on the other one but the Material will ignore that.
Make sure to work in the Material Mode and set your material to Shadeless so you can see the texture better.
